[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0022] The stator coil winding loading device is a key automation device in the motor manufacturing process. It is mainly used to automatically deliver the stator to be wound to the winding position and position it to facilitate subsequent winding work. This automated loading device greatly improves production efficiency, replaces traditional manual loading and unloading methods, reduces workers' labor intensity, and improves production quality.

[0023] like Figure 1-5 As shown, the present embodiment provides a loading device for stator coil winding, including a stator loading device main body 1 and a stator main body 3. A limit assembly 2 is provided above the stator loading device main body 1. The limit assembly 2 is used to limit the loading of stator main bodies 3 of different sizes. The limit assembly 2 includes a rack 23 and an extrusion plate 24. In the prior art, the loading device for stator coil winding is inconvenient to clamp and load stators of different models during the stator loading process, and the stator is easily dropped and damaged. Damage to the stator will affect the continuity of the coil winding work, affect work efficiency, and have low practicality. Therefore, to solve this problem, the stator coil winding loading device provided in the present application is specifically as follows: the sliding rack 23 drives the extrusion plate 24 to squeeze the inner wall of the stator main body 3, driving different models of stator main bodies 3 to perform limited conveying and loading, preventing the stator main body 3 from falling from above the stator loading device main body 1, damaging the stator main body 3 and causing losses, thereby improving practicality.

[0024] Among them, the working principle of the loading device for stator coil winding is mainly to automatically deliver the stator to be wound to the winding position and position it through an automated mechanical device to facilitate subsequent winding work. The components of the stator coil winding device include a rotating mechanism, a sliding device, a clamping device, a lifting device and a cutting device. The stator coil winding device is a complex system that integrates multiple functions and technologies. Each component carries a specific function, which together ensures that the winding work of the stator coil can be carried out efficiently and accurately. This is common knowledge among people in this technical field and will not be elaborated here.

[0025] The improvement of this embodiment is that:

[0026] When it is necessary to load stator bodies 3 of different models, the stator body 3 is placed outside the limit assembly 2, and the two racks 23 are slid in the opposite direction so that the outer wall of the extrusion plate 24 at the end of the rack 23 contacts the inner wall of the stator body 3. The two extrusion plates 24 fix the stator body 3 on the outer wall. After ensuring that the extrusion plates 24 are fixed in place, the stator body 3 can be transported and loaded. The fixation of the extrusion plates 24 prevents the stator body 3 from falling from above the stator loading device main body 1 during the loading process, thereby improving practicality.

[0027] The outer wall of the extrusion plate 24 is tightly fitted with the inner wall of the stator body 3, and the limiting component 2 will limit the stator body 3 of different models, and stably convey the stator body 3 when the stator feeding device main body 1 conveys the stator body 3.

[0028] Taking into account that it is inconvenient for the user to rotate the gear 22, the upper end of the gear 22 is coaxially fixedly connected to a rotating rod 221, and the rotating rod 221 rotates on the inner wall of the fixed column 21. The upper end of the rotating rod 221 is fixedly connected to a rotating cap 222. A number of protrusions are evenly arranged around the outer wall of the rotating cap 222 to facilitate the user to twist the rotating cap 222. The rotating cap 222 drives the rotating rod 221 and the gear 22 to rotate on the inner wall of the fixed column 21.

[0029] Taking into account that the friction between the stator body 3 and the upper surface of the stator feeding device body 1 will damage the stator body 3, the lower end of the fixed column 21 is fixedly connected to the chassis 25, and the lower surface of the chassis 25 fits the upper surface of the stator feeding device body 1. The lower end of the chassis 25 is fixedly connected to the sliding column 26. The upper surface of the stator feeding device body 1 is provided with an open slide groove 10, and the outer wall of the sliding column 26 slides on the inner wall of the open slide groove 10. During the movement of the limit component 2, the chassis 25 supports the stator body 3 to prevent the limit component 2 from being adjusted out of place, causing severe friction between the lower surface of the stator body 3 and the upper surface of the stator feeding device body 1, resulting in damage.

[0030] Considering that the limit assembly 2 needs to be moved for loading, the lower end of the sliding column 26 is fixedly connected to the support frame 261, and rollers 27 are rotatably connected on both sides of the support frame 261. The interior of the stator loading device body 1 is a hollow structure, and the rollers 27 roll in the inner cavity of the stator loading device body 1. The rollers 27 drive the support frame 261 and the sliding column 26 to move inside the stator loading device body 1, and the sliding column 26 slides on the inner wall of the open slide groove 10.

[0031] Considering that it is inconvenient for users to rotate the roller 27, a motor 28 is fixedly connected to the end of the roller 27. The output shaft of the motor 28 drives the roller 27 to rotate, saving time and effort in manually rotating the roller 27, thereby improving work efficiency.

[0032] Among them, the motor 28 is a motor commonly used in the prior art, and its working principle is: an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. This is common knowledge among people in this technical field and will not be elaborated here.

[0033] Taking into account that the motor 28 needs to move as a whole with the limit assembly 2, a sliding groove 29 is provided on the outside of the stator feeding device body 1. The inner wall of the sliding groove 29 is slidably connected to a sliding plate 291. The outer wall of the sliding plate 291 is fixedly connected to the motor 28. The output shaft of the end of the motor 28 extending out of the outer wall of the sliding plate 291 is fixedly connected to the end of the roller 27. During the movement, the sliding column 26 drives the sliding plate 291 to slide inside the sliding groove 29. The sliding plate 291 drives the motor 28 on the outer wall to move synchronously, which makes it convenient to use the motor 28 to drive the limit assembly 2 to move as a whole for loading.

[0034] In summary, the working principle of this solution is as follows:

[0035] When the stator coil winding feeding device of the present invention is used, the stator body 3 is placed on the outer wall of the fixed column 21, and the rotating cap 222 is rotated. The rotating cap 222 drives the rotating rod 221 and the gear 22 to rotate on the inner wall of the fixed column 21. The rotation of the gear 22 drives the two symmetrical racks 23 of the outer wall to slide in opposite directions on the inner wall of the slide groove 211. The rack 23 drives the extrusion plate 24 at the end to squeeze the inner wall of the stator body 3, and the outer wall of the extrusion plate 24 is tightly fitted with the inner wall of the stator body 3. The limiting component 2 will limit the stator bodies 3 of different models, and stably convey the stator body 3 when the stator feeding device main body 1 conveys the stator body 3 to prevent the stator body 3 from falling from above the stator feeding device main body 1, damaging the stator body 3 and causing losses. After the sub-body 3 is fixed, the motor 28 is turned on, and the output shaft of the motor 28 drives the roller 27 to rotate, and the roller 27 drives the support frame 261 and the sliding column 26 to move inside the stator feeding device body 1, and the sliding column 26 slides on the inner wall of the open slide groove 10. During the movement, the sliding column 26 drives the sliding plate 291 to slide inside the sliding groove 29, and the sliding plate 291 drives the motor 28 of the outer wall to move synchronously, so that the motor 28 can be used to drive the limit assembly 2 to move as a whole for loading. During the movement of the limit assembly 2, the chassis 25 supports the stator body 3 to prevent the limit assembly 2 from being adjusted out of place, causing severe friction between the upper surface of the stator body 3 and the upper surface of the stator feeding device body 1, resulting in damage. The stator body 3 can be transported to the unloading point and removed.
